“Summary of my experience with these:
Build: Feels cheap and plasticky. In fact the box appears better made than the earphones. :)
Treble: Very detailed, forward and sharp. No real sibilance BUT is very fatiguing after even after short listening sessions
Mids: Again very detailed but there appears to be some forward and some recessed elements depending on the track you are listening to. The...” --Krisman

“Very nicely balanced overall. Bass very slightly lacking, but this is a matter of taste. Lots of tips to choose from, and came with foamies!

After further burn-in, my Betas became very bass...” --inline79

The M3 that has nothing to do with the same-named German car (J) except for the name...” --HiFiChris

“I bought this in 2012-06, when my Brainwavz M2 broke. It was given a Sonic Diamond by ClieOS for the pre-order price and 4.2 / 5 for the sound quality, so I expected quite a bit.
Unfortunately, the cables are nowhere near as good as those used on the M2. The build quality of the speakers seems quite okay, though.
Compared to the M2, the bass is considerably weaker, but the...” --Kadano
